What step of meiosis in a diploid cell is shown above?
(Hint explains the picture)
Prophase I (early)
The chromosomes begin to supercoil (condense) making them more visible.
What step of meiosis in a diploid cell is shown above?
(Hint explains the picture)
Prophase I (late)
The chromatids' have supercoiled into matching chromosomes. The nuclear envelope disintegrates. Crossing over may happen (entirely random). Spindle microtubules have begun to form.
What step of meiosis in a diploid cell is shown above?
(Hint explains the picture)
Metaphase I
The spindle microtubules move the homologous pairs to the equator of the cell. The orientation of paternal + maternal chromosomes is random and independent of other homologous pairs.
What step of meiosis in a diploid cell is shown above?
(Hint explains the picture)
Anaphase I
The homologous pairs are separated. On chromosome of each pair moves to each pole.
What step of meiosis in the haploid cells is shown above?
(Hint explains the picture)
Telophase I
Chromosomes uncoil then interphase follows. The chromosome number is reduced from diploid to haploid. Cytokinesis occurs.
What step of meiosis in the haploid cells is shown above?
(Hint explains the picture)
Prophase II
Chromosomes, still consisting of two chromatids, condense and become visible.
What step of meiosis in the haploid cells is shown above?
(Hint explains the picture)
Metaphase II
the spindle microtubules line up the chromosomes along the equator.
What step of meiosis in the haploid cells is shown above?
(Hint explains the picture)
Anaphase II
Centromeres separate and chromatids are moved to opposite poles.
What step of meiosis in the haploid cells is shown above?
(Hint explains the picture)
Telophase II
Chromatids reach opposite poles. Nuclear envelop forms. Cytokinesis occurs.
